Short summary
Short summary
For 20+ years, the Commonwealth Science Industry and Research Organisation (CSIRO) has been developing a biogeochemical (BGC) model for coupling with a hydrodynamic and sediment model for application in estuaries, coastal waters and shelf seas. This paper provides a full mathematical description (equations, parameters), model evaluation and access to the numerical code. The model is particularly suited to applications in shallow waters where benthic processes are critical to ecosystem function.

This paper highlights the changes in ocean temperatures and currents that are likely to affect the Great Barrier Reef in coming decades - affecting an iconic and unique environment. It uses newly available high-resolution coupled climate model output to assess the ocean warming and analyses the causes and repercussions of such warming due to climate change.

Short summary
We examined projected changes in Coral Sea temperature and currents through to 2050 using high-resolution CMIP6 models. Surface warming deepened by 30 m per decade, reaching 400 m by 2050. There was sub-surface cooling between 400 and 600 m. North Vanuatu Jet and North Caledonian Jet transports weakened, and the South Caledonian Jet strengthened. These changes may influence western boundary currents and upwelling dynamics on the Great Barrier Reef.
